NFPS / Private What Client to use in Jarvis

IPTV Private Server (NFPS)
I have Stalker Client NFPS 0.8.4 & Stalker PVR Client 1.0.3 which had all my previous settings in when I upgraded from Isengard, but when I enable 1.0.3 it just keeps coming up with 'Failed to connect to server'. Do I need to add additional settings or am I now using the wrong client?

Thx
